Analyzing Benford’s Law’s Powerful Applications in Image Forensics

Applied Sciences, 2021
The Newcomb–Benford law states that in a set of natural numbers, the leading digit has a probability distribution that decays logarithmically. One of its major applications is the JPEG compression of images, a field of great interest for domains such as ...

Prevalence of insulin dysregulation in a sport horse population as determined by traditional and stall‐side testing

Equine Veterinary Journal, EarlyView.
Abstract Background The prevalence of insulin dysregulation (ID) has not been investigated in sport horses. Stall‐side insulin assays offer convenience but need further validation. Objectives To determine the prevalence of and risk factors for ID in a sport horse population using an oral sugar test (OST) and assess agreement between stall‐side and ...

Age‐related local versus systemic early phase wound healing dynamics following free gingival graft harvest

Journal of Periodontology, EarlyView.
Abstract Background Free palatal gingival grafts (FGG) are commonly harvested during mucogingival procedures. The present study investigates age‐related local and systemic early secondary wound healing outcomes, following FGG harvest in a rat model. Methods A 4.2 mm diameter defect was created in the palate of 24 younger (2 m) and 24 older (6 m) Wistar

A manipulação temporária de arquivos JPEG afeta a densidade óptica das imagens?

Revista da Faculdade de Odontologia de Porto Alegre, 2005
Para avaliar se a manipulação temporária de imagens digitais armazenadas no formato JPEG altera a sua densidade óptica, 26 radiografias periapicais de arquivo foram digitalizadas através de scanner, armazenadas no formato JPEG 12 e digitalmente ...

Oxygen transmission rate in American oak barrel staves used for wine aging: Influence of wood macrostructure

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Background Oak barrels are widely used in wine and spirit aging, where oxygen transmission plays a key role in the development of chemical and sensory properties. In cooperage, stave selection is traditionally based on grain width; however, the extent to which grain and wood macrostructure determine oxygen transmission under barrel conditions ...

Hamming Code in JPEG Image Steganography within the Discrete Cosine Transform Domain

Journal of Applied Informatics and Computing
This study proposes a novel JPEG image steganography method that combines Least Significant Bit (LSB) embedding in the Discrete Cosine Transform (DCT) domain with Hamming Code (2k − 1, 2k − k − 1) to minimize the number of modified DCT coefficients ...

A Statistical Modeling Framework for DCT Coefficients of Tampered JPEG Images and Forgery Localization

IEEE Access, 2022
Various manipulations on JPEG images introduce single and multiple compression artifacts for forged and unmodified areas respectively. Based on the statistical analysis of JPEG compression cycle and on the finite mixture paradigm, we propose in this ...

Practical considerations for pathologists when selecting digital pathology systems: an ESDIP guide

The Journal of Pathology, EarlyView.
Abstract The implementation of digital pathology (DP) has been reported across academic, public, and private laboratory settings, providing valuable insights into workflow transformation. However, comparatively little guidance exists on how DP systems should be evaluated prior to acquisition and deployment.
